the chemical indicator used is iodine
and
starch turns in dark blue colour
ARE U HAPPIEE WID MA ANSWER ?
THANKU
The iodine test can indicate the presence of starch in food samples. When iodine is added to a sample containing starch, it will turn blue-black in the presence of starch. This color change is used as a visual indicator for the presence of starch in the food sample.
Iodine is used as an indicator because it changes color in the presence of starch. When iodine comes into contact with starch, it forms a blue-black complex. This color change is easy to observe and is used in various chemical tests to detect the presence of starch.
Starch turns a deep blue-black color when broken down due to the presence of amylose and amylopectin reacting with iodine. This color change is used as a common indicator of the presence of starch in various experiments and tests.
Starch indicator solution will remain its original color (usually colorless) in the absence of starch. Without starch present, there will be no color change observed when using starch indicator solution.
Chemical indicator dye is a substance that changes color in the presence of a specific chemical or changes in pH. It is commonly used in laboratories to visually indicate the presence or absence of certain substances in a solution.
Starch is not the indicator. Iodine is the indicator of starch.
Iodine is commonly used as a chemical indicator for the presence of starch. When iodine comes into contact with starch, a blue-black color change occurs, making it easy to visually detect the presence of starch in a solution.
Iodine turns it purple in the presence of starch. :D~PiNkBuN17 Aka Aisha

Iodine is used as an indicator for starch. When a substance has iodine added to it, then it will turn into a dark blue color. This is a sign that the substance indeed has starch in it.

The fat titties that I have that boys in my school stare at indicate the boners to the boys with smelly cocks.
The chemical used to test for the presence of starch is iodine.
When an indicator such as iodine is added to a solution containing starch, a blue-black color change occurs. This reaction is commonly used to detect the presence of starch, as the blue-black color is characteristic of this complex formed between the starch and iodine molecules.
The indicator for starch is iodine solution. Iodine changes color from brown to blue-black or purple-black in the presence of starch.
The starch iodine complex is significant in chemical reactions because it is used as an indicator to detect the presence of iodine. This complex forms a blue-black color when iodine is present, allowing scientists to visually confirm the occurrence of certain chemical reactions, such as the conversion of starch to sugars.
Iodine turns blue-black in the presence of starch. This is used as an indicator in laboratory experiments to detect the presence of starch in a solution or material.
